FAQs

Genuine grease consists of oils and/or other liquid lubricants mixed with thickeners (usually soaps) to form a solid or semi-solid. Greases are typically shear thinning or pseudoplastic liquids. In other words, shear reduces the viscosity of the liquid.

Common Grease Types and Characteristics :-

• Aluminium Complex Grease
• Bentone (Clay) Grease
• Calcium Grease
• Lithium (12-Hydroxy Stearate) Grease
• Lithium Complex Grease
• Polyurea Grease
• Sodium Grease (Soda Soap)

Fats are commonly used for: Machines that operate intermittently or that are stored for long periods of time. Since the grease stays, a lubricating film is immediately formed. Machines that are not easily accessible due to frequent greasing.

There are several methods of gearbox lubrication, the most common being grease lubrication, oil splatter and forced oil. Grease lubrication is suitable for low speed operation, but is less effective than oil for cooling and is not recommended for continuous operation or high load applications even at low speed.

The most commonly used grease is NLGI #2. Softer grades are often used for increased pumpability or low temperature operation, while harder grades are used where leaks and seals are particularly important. The Cone Penetration Test (ASTM D217) measures fat consistency.

The function of grease is to contact and lubricate moving surfaces without being spilled by gravity or centrifugal force or pushed out by pressure. A great practical advantage of greases is that they retain their properties under shear at all temperatures they are exposed to during use.

For example, gear oils may contain sulfur-phosphorus extreme pressure (EP) additives. First make the fat thickener and then add the oil to achieve the desired quality. Therefore, when oils and fats are mixed, the ratio of base oil and thickener changes and the consistency decreases.

Mixing two incompatible greases usually results in one of two things:
Either the mixture hardens and releases no oil, or the mixture softens and releases all the oil. In both cases the end result is basically the same. Virtually no lubrication.

Grease is better at controlling leaks and provides a better seal against contaminants. Grease stays on gears longer and can withstand a wide range of conditions. It is also easy to use in most industrial environments.

Food grade greases are lubricants made from synthetic materials that provide high performance without compromising safety or health. Food grade fats are used for:
Fast and slow chains. rollers and bearings.

There are two basic grease types for most equipment and mechanical applications.
NLGI #1 Grease and NLGI #2 Grease. With less thickener, #1 grease is easier to handle and slippery, while #2 grease has more thickener, which makes it stiffer and better for general purpose applications. .

Food grade greases are lubricants made from synthetic materials that provide high performance without compromising safety or health. Food grade fats are used for:
Fast and slow chains. rollers and bearings.

If there is too much grease in the bearing cavity (overlubrication), the rotating bearing elements will start churning the grease and pushing it out of the way, causing energy loss and temperature rise. This accelerates the wear of the rolling elements and can lead to component failure.

Commonly used in food and beverage processing equipment, aluminum complex greases are food grade greases made with food grade white mineral oil or synthetic hydrocarbons.

High temperature greases were developed to meet the need to protect high speed bearings in high temperature and mechanically loaded applications. It has a dropping point of 625 degrees Fahrenheit, making it perfect for cold weather.

A grease that provides excellent lubricity and protection against corrosion in wet and humid environments. It resists water run-off and allows grease to stay in place in the presence of water to protect against rust and corrosion.

Calcium sulfonate grease is made by converting a liquid detergent containing amorphous calcium carbonate into a grease containing calcite particles. Performance additives containing sulfur, phosphorus, or zinc may not be necessary due to the lubricating properties of calcite particles.

This grease stays stably in place even under high pressure, heavy loads and shock loads. Commonly used in demanding mining, construction and automotive applications.

The polyurea base lasts four times longer than regular grease and only needs to be reapplied once a year. This grease is designed for high speed applications and is plastic safe.
